Motola didn't even know Momma, her sheep, was pregnant from a rendezvous with Michael, a goat. This case is so rare that no one is really sure what to call Butterfly except a geep.

A ham for photos with visitors and local news organizations, she is the only reported breed of her kind in the nation.

This cutie has the features of a goat, but the woolen coat of a lamb, AZ Central reported.

In April, BBC News reported Ireland's first birth of a geep, where a goat mated with a sheep belonging to a sheep farmer. Before that, a geep birth had been reported by TIME magazine in Botswana in 1984.

The Irish farmer said he noticed his geep, "was able to run faster than other lambs that were born around the same time," the newspaper reported.

Geep are quite rare because goats and sheep hardly mate, and when they do their offspring are stillborn according to a report by KHON2.

"This is really uncommon," Motola said said. "It's the first time it's ever happened here, and I've been doing so much research, finding there aren't very many in the world."

So far Butterfly is healthy and happy, "jumping around, nursing and playing with her mom," Motola said.
